SPECIFICATION forming part of Letters Patent No. 512,443, dated January9, 1894.

Application filed December 23, 1892. Serial No. l56,148. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS KERSHAW, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inFeeding Devices for Carding-Machines; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in feeding devices for the secondbreaker and nisher of carding machines and has for its obj ect., theprovision of an improved construction in various parts of the feedingdevice, whereby an even delivery of the web or roving is made on allparts of the feed table, an even delivery to the card cylinder issecured and perfection in the outside strand of the web is attained, sothat the entire web can be spun into yarn without the Waste upon thesides which is necessitated by all of the feeding devices now in use, sofar as I am aware.

My invention contemplates improvements in the form of web which isdelivered to the feeding device, improvements in the position and mannerof mounting the feed or traverse rolls, improvements in the manner ofgearing and operating said rolls, improvements in the mechanism forconnecting the traveling frame with the chain or belt, the provision ofmeans for the accurate adjustment of the distance which the traverserolls move and the proA vision of means for controlling the delivery ofthe proper quantity of stock to both sides of the feed apron. Y

Theinvention will be understood from the following detail descriptionand will be finally pointed out in the claims.

In the accompanying drawings Figure l, is a perspective view showingparts of the two carding machines (second breaker and inisher) with myfeeding device attached. Fig. 2, is an elevation of the traverse rollsmounted in the frame carrying same. Fig. 3, is an elevation of thetraverse rolls andframe with the gear wheels removed from the rolls.Fig. 4, is an elevation of the slide device which connects the travelingcasting with the driving chain or belt showing a sprocket wheel indotted lines to avoid obscuring the view of the traveling casting. Fig.5, is a vertical section of Fig. 4. Fig. 6, is a detail view showing aHaring reciprocating guide attached to each side ot the feed table.

. Similar letters of reference indicate corresponding parts in all thefigures where they occur.

I have not deemed it necessary to illustrate more than the immediatelyadjoining portions of the carding device with which my improvement isintended to co-operate.

A, is a portion of the first cai-ding machine from which the web istaken in a flat cordition, it being doffed upon a traverse apronattached thereto; from this traverse apron the flat stock passes betweenthe draw rolls a, a, which press. it into a condition of sufficientstrength to carry it over the overhead rigging a', a. The webafterleaving the overhead rigging is carried directly down to the traverserolls h, b, which are set horizontally and deliver the untwisted webdirectly upon the feed table without its being twisted or turned fromV adirect line. The traverse rolls are mounted in a frame which isadjustably secured upon a traveling casting C, which rides upon theguides D, D. pivoted to the traveling casting C, by means of a singlebolt X, as shown in Fig. 5, so that the position of the traverse rollscan readily be shifted to bring their axes at any desired angle to theface of. the carding cylinder of the second machine. The guide bars D,D, afford a double bearing, one at top and the other at the bottom forthe traveling casting. These bars are set at an angle of about fortylive degrees more or less from the face line of the card cylinders. Thetraverse rolls are set in such a position as to be at, or nearly at, aright angle to the face of the carding cylinder, and this position canbe accurately secured or varied as desired, by means of the The rollframe B, is

adjusting device (bolt X), connecting the roll frame to the travelingcasting as already described. It is essential to good work and tosecuring perfection lin the outside strands to have the traverse rollsset in the position described, in order that the proper amount of stockor web is delivered upon the space on IOO the feed table opposite toeach ring on the doffer of the finishing card and that said traverserolls deliver the web and double it at each side of the feed, laying thecoupled over parts or ends in a. straight line at or nearly at rightangles to the face of the carding cylinder of the second machine.

The traverse rolls are provided at their outer ends with gears orfriction pulleys b', b', and a driving gear or pulley b2, is mounted ona swinging support b3, which allows said driving pulley or gear to betumbled from one traverse pulley or gear to the other, as thereciprocation of the traverse rolls takes place.

Secured to the driving pulley or gear and freely revolving with' it on asuitable stud attached to the swinging support is a drum or pulley b4,around which is wound a band or cord b5, which passes around suitableguide spools h6, loosely mounted on upright arms secured to the sides ofthe frame B, in any suitable manner and is provided at one end with aweight or spring bi, and fastened at the opposite end in any suitablemanner. This cord may be fastened securely at both ends, but it answersthe purpose better when one end is weighted, thus keeping it at alltimes taut. This arrangement of the cord b5, and the drum b4, serves tothrow the driving pulleyor gear b2, from one traverse pulley or gear tothe other at the beginning of each reciprocating movement of thetraverse rolls, thus keeping the rotation of the rolls in the properdirection for feeding the web, it being understood, of course` that thetraverse pulleys or gears actuate each other.

To insure that the reversing movement of the traverse rolls shall takeplace immediately upon the change of the reciprocating movement of thetraveling casting C, the eX- tending arms c, c, are loosely secured orjointed upon the upper end of the swinging support b3, these armsprojecting beyond the spools b, along the cord b5. (See Figs. l, 2, and3.)

c', c', are stops securely fastened upon the cord at each side of thefeed at a point where the arms c, will strike against it, just beforethe reciprocating movement of the traveling casting C, changes. As aconsequence the swinging support b3, is positively forced over and thedriving gear or pulley b2, moved in an opposite direction and engagingwith the other one of the gears b.

E, is a chain or belt that carries the traverse rolls back and forthacross the machine. This chain or belt is mounted upon sprockets orpulleys e, c', which are supported upon brackets held by the end postsof the feeding device, and if desired may be longitudinally adjustabletherein. It will be seen that the chain may be lengthened or shortenedby putting in or taking out a link, the sprockets being movedcorrespondingly back or forward. The pulley or sprocket e, carries abevel gear on the opposite end of the stud; this bevel gear meshes witha similar gear in a diagonal -arbor which is set in this position inorder to be parallel with the axes of the card cylinder and carries apulley e2over which a belt passes to a suitable driving pulley on thecarding machine to give motion to the driving chain 0r belt E. Thetraveling casting carries an upright guide f, which engages with aswivel piece f', which is swiveled or loosely connected tothe drivingbelt or chain so as to afford easy action, as the swivel piece f',passes around the sprockets or pulleys upon which the driving chain orbelt is mounted. The swivel piece f', rides up and down on the guidef,and turns on its pivot or swivel to accommodate the movement around thepulleys or sprockets.

In order to increase the distance which the traverse rolls cover intheir respective movements to deliver the required amount of web infront of the outside doler rings, Ilengthen or shorten the chain or beltand correspondingly move the brackets on which the sprockets or pulleysare mounted, but this does not give a fine adjustment and requiresconsiderable time to accomplish. I have therefore provided an adjustingdevice upon the traveling casting, by means of which I can set thelateral movement of the upright guidef, with certainty and precision. Toeffect this lateral adjustment of the upright guide f the travelingcasting is provided with a `longinal way C into which fits and slides astud f2 on the back of asliding bracket F, as shown in Fig. 5. Thisbracket F whichslides back and forth in the horizontal way C in thetraveling casting C has ears or projections fs at its top and bottominto which is secured the upright guide f upon which slides the swivelpiece f and connects the said upright guide to the carrier chain, andthrough it the sliding bracket F and the traveling casting C are alsoconnected with the said carrier chain for the purpose of carrying saidtraveling casting back and forth upon the rods D, as is evident.

g, g, are set screws in the traveling casting at each end of the way Cfor limiting the distance of the slide of thebracket F. By means ofthese set screws it will be apparent that the sliding bracket F can beheld rigid at any point in the way C that may be desired, by sliding itto the desired point and then forcing the screws against either side ofit; itcan be slid back and forth throughout the whole length of the wayC', or its sliding movement can be limited by adjusting the said screwsto any length less than the length of the way C', and to any portion ofthe way C', that is, the sliding of this bracket F can be confined tothe middle portion of the way C', or to either the right or left handportion of the said way C', as may be. desired. From this IOC" IIO

construction of the adjusting device it is evident that if the traverserolls lay the stock too close to the edge of the machine, this can beremedied by increasing the distance of the movement of the slidingbracket F by means of the set screws g, g, which will shorten thcdistance traveled by the traveling casting, and consequently that of therolls carried thereby. If the stock is not laid close enough to the edgeof the machine, the length of the movement of the sliding bracket isdecreased, by means of the set screws, whereby the length of themovement of the traveling casting will be increased, and consequentlythe movement of the traverse rolls carried thereby. By this constructionloan so adjust the lnovement of the sliding bracket F that it willregulate the feeding of the stock upon the machine at both, or at eitherside, or at one side and not at the other as circumstances may require.As the sliding bracket F, is securely attached to the chain E, it mustalways travel a uniform distance across and back,`that distance beingthe length of aline drawn through the center of the sprocket wheels andextending from the outside of one sprocket wheel to the outside of theother sprocket wheel. Vhen. the bracket is held rigidly at any one pointin the traveling casting C and not allowed to slide therein, thetraveling casting will be carried exactly the same distance that thebracket F is carried.

' If the bracket F is allowed to slide along in the way C', the distancethat the traveling casting C, is carried will be reduced just as much asthe bracket F slides in the way C', for the reason that while thebracket F is sliding along in the way'G, the traveling casting mustnecessarily remain stationary, not being affected by the forwardmovement of the bracket until the said bracket is carried along andstrikes against one of the set screws g. The traveling casting C, beingmoved by the chain E, acting through the bracket F, and causing saidbracket to impinge against one of the set screws g, it can move only asfast as the chain moves, and it follows, that if the traveling castingremains stationary at any time while the chain and slide are moving, thedistance that the traveling casting C, is carried in a given time wouldbe less than the distance that the chain and slide move in the sametime, the difference being the distance that the chain and slide movewhile the traveling casting remains stationary, t'. e., the length ofthe slide of the bracket Fin the way C.

in Fig. 4 of the drawings the traveling casting C, is shown as beingcarried by the chain E, from left to right, with the sliding bracket Fpressing up against the right hand setscrew g. When the chain has movedfar enough to carry the swivel piece f and the attaching link in thechain E, around the sprocket wheel, the movement of the bracket F, willbe reversed and it will go from right to left.

The movement of the traveling casting C,

however, will not be immediately reversed, but it will remain stationaryuntil the sliding bracket F, moves along in the way O and strikesagainst the set screws g, on the left hand side of Fig. 4. Any desiredmechanism for effecting this result may be employed without departingfrom this invention, but I prefer to use that shown and hereindescribed.

In order to retain the web at any particular point op the side of thefeed, with more certainty and precision, and to take in any stray orstraggling ends, or fibers that may stick out,-I piace at the sides ofthe said feed, the adjustable guides L, L, shown in Fig. 6. These guideshave flaring ends, l, l, and are loosely mounted on the studs l', beinggiven areciprocating movement by the rocking shaft L. The flaring endsof these guides take in all straggling fibers, after which they aregently forced into the required space on the feed table.
